Figure 3. NVMe cable routing
The following illustration shows four NVMe cable connection options, but the four options are mutually exclusive. Select one of them based on your scenario.
|1 Signal connector on the M.2 drive backplane||M.2/7mm backplane signal connector on the system board assembly||Signal connector on the M.2 drive backplane||1 PCIe 1|
|2 PCIe 3 (one CPU installed)|
|3 PCIe 8|
|4 PCIe 10|
